The best description of nutrient runoff is that it involves nutrients washing away from the soil into waterways. This phenomenon typically occurs during rainfall or irrigation when excess water moves over the land surface. As the water flows, it can carry away soluble nutrients, such as nitrogen and phosphorus, which can lead to water quality issues like algal blooms in lakes and rivers. Runoff is a significant environmental concern because it can negatively impact aquatic ecosystems and contribute to problems such as eutrophication.

The other options represent processes that do not align with the concept of nutrient runoff. Nutrients being absorbed by plants refers to uptake by root systems rather than loss from the soil. Nutrients being locked in the soil describes a stable condition where nutrients are unavailable for runoff. Finally, nutrients being naturally recycled in the environment refers to a process by which nutrients are returned to the soil through organic matter decomposition, which, while important, does not reflect the movement of nutrients away from the soil as runoff does.
